Abstract: Perfume compositions comprise at least 50% by weight of ingredients characterized by (i) having a molecular formula possessing from 8 to 13 carbon atoms, none of which form part of phenyl moieties, substituted or unsubstituted; (ii) an octanol/water partition coefficient (logP) of at least 2; (iii) a saturated vapour pressure (SVP) of at least 5 micron Hg at 25° C.; and (iv) belonging to one of the following groups: 1) ethers of general formula R1OR2; 2) aldehydes or nitriles R1X, wherein X is a formyl group or a cyano group; 3) esters R1CO2R2; 4) alcohols R1OH; 5) ketones R1COR2; wherein R1 and R2 are hydrocarbyl residues, straight chain or branched, and optionally substituted, and may be linked as part of a ring structure. The compositions find particular application in the form of encapsulates for use in consumer products.

Abstract: A perfume composition effective in reducing or preventing malodours comprises at least 1.0% by weight of one or more materials having a fruity note; and at least 0.5% by weight of at least one material having an amber note and selected from group A and/or from group B below, wherein the total amount of material having an amber note and material having a fruity note in the composition is at least about 3% by weight if no amber material from group B is present, or at least about 25% by weight if no amber material from group A is present, and where materials from both groups A and B are each present in an amount of at least 0.1% w/w the total amount of amber and fruity materials together is at least 3% by weight where the total weight percentage of group A materials, WA, is equal to or greater than 0.5% or the total amount of amber and fruity materials together is at least 3+22*(0.5?WA) % by weight where WA is less than 0.

Abstract: The invention concerns the control of body odours, particularly odours (other than axillary malodour) associated with body fluids and solids, by use of low odour compositions of fragrance materials. The composition of fragrance material preferably includes at least 5 of one or more musks and at least 5% of one or more salicylates.

Abstract: The invention concerns the control of female body odours, particularly odours associated with body fluids, namely products of the genito-urinary tract, such as menstrual or catamenial fluids, vaginal fluids, urine, by use of low odour compositions of fragrance materials. The composition of fragrance material includes at least 5% of one or more musks and at least 5% of one or more salicylates.

Abstract: A perfume composition comprising a perfume component capable of inhibiting the production of odoriferous steroids by micro-organisms on the skin. The perfume component is capable of inhibiting the biotransformation of androstadienols to androstenones.
